I don’t want to work through my phone or my brothers laptop anymore.
Now,I have a couple of options(they aren’t cheap,but I think they’re the best ones for me because I can’t work with windows)
iPad Pro 12.9 (2020)
MacBook Air
MacBook Pro
Which one do you think is the most comfortable and fits to this kind of business? Also take notes that I need to do some designs for promos and posts.
Hope someone can give me honest opinion to help me decide because it’s not cheap....
